It is located south of Tom's Place and Crowley Lake in the eastern part of the Sierra Nevada range. South of the summit, the road starts on its long 2,400 foot (610 m) descent into the 4,000 ft (1,200 m) high Owens Valley. The Owens River generally follows the road from this summit through the Owens Valley. Motorists who come from the south usually cross this summit in order to go to the high-altitude towns like Mammoth Lakes to the northwest to escape the smothering summer heat in the deserts. The pass receives snowfall during the winter, although the region receives relatively little precipitation annually.

This stretch of the creek, looking upstream to the southwest, has long been a popular recreation area because of the warm waters from its thermal springs. These springs, however, are unpredictable and can suddenly erupt with violence and at boiling temperature. Because of this danger, the U.S. Forest Service has had to close parts of the Hot Creek Geologic Site to visitors.

Long Valley was formed 760,000 years ago when a huge volcanic eruption released very hot ash that later cooled to form the Bishop tuff that is common to the area. The eruption was so colossal that the magma chamber under the now completely destroyed volcano was significantly emptied to the point of collapse. The collapse itself caused an even larger secondary eruption of pyroclastic ash that burned and buried thousands of square miles. Ash from this eruption blanketed much of the western part of what is now the United States. Geologists call topographic depressions formed in this manner calderas..

Mammoth Mountain (11,050 feet), is a composite volcano made up of about 12 rhyodacite and quartz latite domes extruded along the southwest rim of Long Valley Caldera from 200,000 to 50,000 years ago. Mammoth Mountain is one of the eruptive centers that developed late in the evolutionary cycle of the Long Valley Caldera complex.
